Former Sun editor Kelvin MacKenzie will be no stranger to the tactic of doorstepping, so Channel 4 News chief correspondent Alex Thomson sought to give him a taste of his own medicine when he turned up at his home to ask him about his coverage of Hillsborough. MacKenzie was less than keen to talk ("I'm not going to do it, I will talk about it next week," said the former Sun man) but a persistent Thomson wasn't giving up. So much so that he wedged himself in between MacKenzie and his car door, preventing the ex-editor from driving off. Here's a taste of the pair's increasingly testy exchange. Kelvin MacKenzie: "Can I close my own door?" Alex Thomson: "Not until you have answered that question." KM: "It's not up to you to decide whether I answer the question." AT: "I just did, Kelvin." KM: "Please Alex, it's not reasonable." AT: "That's pretty rich coming from you Kelvin ... The public are going to love that Kelvin ..." MacKenzie, it turns out, is saving himself for next week's Spectator magazine.
